CAN YOU USE KEYWORD INSERTION IN SITELINK EXTENSIONS GOOGLE ADS

The question of whether you can use keyword insertion in sitelink extensions google ads comes up constantly, usually from advertisers who already love what dynamic insertion does inside their headlines and want the same dynamic relevance in their sitelinks. It is a reasonable instinct. If the keyword that triggered the ad can appear in the headline, why not in the sitelink link text right below it? I had the same thought years ago, tested it on live accounts, and the result was clear enough that I have never recommended it since. In this article I am going straight to what actually happens when you try, what serves, what gets disapproved, and the approach I use instead to keep sitelink text relevant to the keyword without any of the risk. If you are still mapping the basics, our guide on what dynamic keyword insertion is covers the foundation this article builds on.

The short answer: no, and here's why

Can you use keyword insertion in sitelink extensions google ads? No. Keyword insertion is engineered for Responsive Search Ad fields, the headlines, the description lines, and the vanity display URL path, and the dynamic insertion engine simply does not process sitelink asset fields. The {keyword:default text} code that swaps in your triggering keyword inside a headline is treated as ordinary characters the moment it lands in a sitelink. There is no mechanism behind the sitelink text field that reads the curly braces as a placeholder, so nothing dynamic ever happens.

This is the part most people miss when they ask whether you can use keyword insertion in sitelinks google ads: the braces do not throw a visible error in the editor. The sitelink often saves without complaint. That apparent success is exactly what creates the confusion, the field accepts the text, so it looks like the feature is supported, right up until you check what actually serves. And what serves is never the inserted keyword.

Google's documentation on how keyword insertion works frames the feature entirely around ad text, headlines and descriptions, with no provision for assets like sitelinks. The absence is not an oversight; sitelink assets are a separate object type from the ad, and the insertion code is bound to the ad creative, not to the asset library.

What I actually saw when I tested it

Rather than rely on the theory, I ran the test the way any account manager would. I took a small Search campaign with tightly themed ad groups and tried pushing DKI code into sitelink fields in three different ways, watching both the review status and what eventually rendered on the SERP.

Test 1, DKI code in the sitelink link text

I set a sitelink link text to {KeyWord:Our Services}, expecting either a rejection or a dynamic swap. Neither happened cleanly. The asset saved, went through review, and then served the literal default, "Our Services", on every impression, regardless of which keyword triggered the ad. The braces and the keyword token were stripped or ignored, and the fallback became the permanent text. So the slot was not wasted exactly, but it behaved like a static sitelink that I had over-engineered for no benefit.

Test 2, DKI code in the sitelink description lines

People assume the two optional description lines under a sitelink work like RSA descriptions because they look identical in the interface. They do not. I placed insertion code in a description line and got the same outcome as the link text: the default text served, the keyword never changed, and there was zero dynamic behaviour. This matters because the description lines are where advertisers most often expect insertion to "just work," and it never does.

Test 3, malformed and aggressive syntax

When I deliberately used incomplete syntax, an opening brace with no default text, the asset was more likely to be flagged and disapproved during review for containing invalid content. That is the rejection side of the question. Well-formed code with a clean default tends to pass review but never function; broken code tends to get rejected outright. Either way you lose, which is the honest answer to whether you can use keyword insertion in sitelinks google ads: you cannot, and the two failure modes are "serves the fallback forever" or "gets disapproved."

Where keyword insertion genuinely works

To be useful rather than just negative, it helps to be precise about where the feature does function, because the boundary explains the sitelink behaviour. Per Google's setup guidance on setting up keyword insertion, the code can be added within the ad's headline, description lines, or vanity display URL path, and nowhere else in the ad.

Notice what is on that list and what is not. Headlines: yes. Descriptions: yes. Display path: yes. Sitelink assets, callouts, structured snippets, the final URL, and Dynamic Search Ads: not on the list, and in practice not supported. The same documentation explicitly notes the feature does not work in Dynamic Search Ads and that customizers cannot be used in the Final URL field. The pattern is consistent, keyword insertion lives inside the RSA creative, and assets attached to the ad are governed by separate rules. Understanding how keyword insertion works in ads makes the sitelink limitation obvious: the placeholder needs the ad-serving layer to resolve it, and that layer never touches asset text.

This is also why match type is irrelevant to the question. Keyword insertion behaves the same across broad, phrase, and exact, because it inserts the keyword rather than the search term, but that behaviour only exists in fields the engine processes, and sitelink fields are not among them.

What to do instead: ad-group sitelinks done right

The goal behind wanting DKI in sitelinks is real, you want the sitelink text to feel relevant to the keyword the user searched. There is a reliable way to get that, and it does not involve any dynamic code. The answer is structuring sitelinks at the ad group level instead of leaning on insertion.

When sitelinks are set at the ad group level, you control which sitelinks appear for which cluster of keywords. For an account with five tightly themed ad groups, I write five small sets of sitelinks, each phrased around that group's specific intent. A group built around "enterprise pricing" gets sitelinks about plans and quotes; a group built around "free trial" gets sitelinks about signing up. That achieves the keyword relevance people hoped to get from dynamic insertion , reliably, and without a single disapproval for syntax. If you are setting these up for the first time, our walkthrough on how to add sitelink extensions covers the ad-group-level placement step by step.

It is more manual than a single insertion string, which is the trade-off. But manual sitelinks that serve and convert beat a dynamic string that either freezes on its fallback or gets rejected. After managing this across dozens of accounts, the pattern never changes: the people who try to force keyword insertion in sitelink extensions google ads spend a week debugging why it "isn't working," and the people who build themed ad-group sitelinks ship in an afternoon and move on. The honest conclusion to whether you can use keyword insertion in sitelinks google ads is no, so stop trying to make the braces work and put that effort into ad-group structure, where it actually pays off.
